7. Setting by LCD module
The output voltage and frequency and bypass state could be set directly
through LCD module. The output voltage could be set to 208V, 220V,
230V and 240V. The output frequency could be set to 50Hz and 60Hz.
The bypass state could be set to enable and disable. But all the settings
could only be done when the UPS is in bypass or no output mode.
In bypass or no output mode, pressing the “Select” buttonontheLCD
panel for more than one second, a flickering black line would be shown
under “208V” on the screen. And if pressing the “Select” button
continuously again, the flickering black line would move to “220V”,nextto
“230V”, “240V” , “50Hz”, “60Hz”, “Bypass Disable”, “Bypass Enable” in turn.
And if pressing the “Enter” button for more than one second at this time,
the flickering black line would turn to flickerless and the output voltage or
frequency or bypass state setting would be modified to the selected value.
And if no any pressing on the “Select” or “Enter” button lasting for more
than ten seconds, the flickering black line would disappear.
The only one voltage value could be selected in “208V”, “220V”, “230V”,
“240V” at any time. The only one frequency value could be selected in
“50Hz”, “60Hz” at any time. And the output voltage and frequency would
be changed to the corresponding value after the right values are selected
on the LCD panel and the UPS is turn on by pressing the “ON” Button.
The UPS would turn to bypass mode in several seconds after “Bypass
Enable”
is selected, and turn to no output mode in several seconds after
“Bypass Disable” is selected.
